<title>Abstract</title> Surrounding rock classification is a critical factor in evaluating tunnel stability, determining construction methods, and selecting support parameters. Various engineering sectors utilize different methods for grading surrounding quality. The HC method iswidely adopted the hydropower industry this purpose. However, due to anisotropy of layered phyllite, results obtained using phyllite tunnels—when layer orientation parallel axis-differ significantly from those based...

This study aims to explore the mechanical behavior of Desert Sand Concrete (DSC) under freeze–thaw (F-T) cycles. By adjusting number F-T cycles, research analyzed impact various desert sand replacement ratios on frost resistance concrete. The focused dynamic changes in mass loss concrete specimens, relative elastic modulus, cubic compressive strength, splitting tensile and axial strength. Scanning electron microscopy was employed analyze micro-morphology specimens after analysis aimed...

There are two kinds of excavation methods in underground engineering: the tunnel boring machine (TBM) and drill-blasting method. A large number studies have shown that deformation failure, degree disturbance, stability reinforcement measures surrounding rock using TBM method vary from each other. To accurately master these macroscopic damages, it is necessary to focus on investigation micro-mechanical responses rock. Scanning electron microscopy tests, acoustic emission tests detection were...

In order to perform virtual reality fitting of a garment through the Internet, an effective method three-dimensional (3-D) modeling is developed. The simulated using 3-D quadrangular mesh based on mass– spring system. To demonstrate dynamical draping behavior particular woven fabrics, material properties adopted in simulation, including tensile, shear, and bending, were measured Kawabata animating garment, minimal enclosure was introduced facilitate fast reliable detection cloth–body...

Abstract. Southwestern China is characterized by many steep mountains and deep valleys due to the uplift activity of Tibetan Plateau. The 2008 Wenchuan earthquake left large amounts loose materials in this area, making it a severe disaster zone terms debris flow. Susceptibility significant factor flows for evaluating their formation impact. Therefore, there an urgent need analyze susceptibility area. To quantitatively predict area flows, study evaluates 70 typical flow gullies, which are...

In this article a practical mass-spring system was developed to simulate the draping of woven and knitted fabrics. The material properties important fabric drape, including aerial density, tensile, shear, bending were measured using Kawabata Evaluation System experimental data incorporated into model dynamic behavior few selected garment made corresponding five types fabrics simulated as well. It found in simulation that experience more deformation with smoother appearance than due their...

It has long been a problem how to objectively evaluate the wet wearing comfortability of fabrics. In this paper novel testing method was proposed, and an instrument designed made. During process, fabric specimen first got saturated by “sweat” adhered on “skin”, then it separated at due rate from skin in time adhesion force-displacement curve drawn simultaneously. When totally skin, maximum force work were measured such as properties specimen. Six different kinds fabrics selected tested. The...

Color performance on textiles is affected by many factors. In order to make the color presented more precisely, it necessary clarify relationship between fabric structure and dyeing effect, so as compensate displayed according different fabrics in matching. Pad of cotton with vat dyes was carried out, principal component analysis used analyze comprehensive properties fabrics. According factor weight, main factors affecting effect were obtained, a mathematical regression model values...
